IMPROVEMENT \i MACHINES FOR ROLLING PAPER.

Specification forming part of Letters Patent No. 183,112, dated October10, 1876; application filed May 27, 1876.

To all whom it may concern Be it known that I, CHARLES T. Brscnor, ofGloggnitz, Austria, have invented a new and Improved Machine for RollingPaper, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a vertical longitudinalsection of my improved machine for rolling paper; Fig. 2, an end view ofthe same, and Fig. 3 a detail cross-section of theseetional winding-upSimilar letters sponding parts.

The object of my invention is to provide for meeting the increaseddemand for rolls of continuous paper, to be used in the printing ofnewspapers by the latest styles of printingpresses, an improved machineor apparatus for rolling paper in rolls of any required widths, andcutting the paper simultaneously with the rolling, so as to furnish therolls wound up in tight and uniform state, ready for packing, shipment,and use.

The invention consists of a sectional roller of longitudinalwedge-shaped center and side of reference indicate corre- 'sections, onwhich the paper is wound from the drum by means of suitable rollers thatproduce the stretching, smoothing, and rolling of the paper. Thecore-roller is movable in slotted side standards, to adjust itself tothe varying diameter of the paper-rolls. Curved and laterably adjustablearms or frames carry revolving cutting-knives and eccentricguiderollers, which are set in motion by pulley and cord connection withatop shaft, to which the and revolved by suitable power, the cylinder Ebeing designed to serve as support to the vertically-sliding roller 0.The roller 0 is made of three detachable longitudinal sections, and ofround cross-section, as shown in Fig. 3, the sections being tapering orwedgeshaped, and connected longitudinally by dovetail tongues andgrooves. The ends of the roller-sections are provided with screw-threadsfor the screw-fastening hands a, that look the sections in the nature ofscrew-nuts. One of the roller-sections is arranged with a longitudinalgroove and spring, I), that serves to retain firmly the end of the paperto be Wound. The roller 0 is readily detached from the center of thepaper-rolls by unscrewing the end bands, and withdrawing the centralsection by suitable mechanism, so that the side sections become loose,and may be readily taken out. The weighted roller D bears on the top ofthe sectional roller 0, and rises in connection with the latter in theslotted standards, according as the thickness of the paper-rollincreases thereon. The paperis passed over the weighted roller, and thenon the sectional roller, the weighted roller serving to produce thesmooth and tight winding up throughout the entire length of the paper.

The paper coming from the paper-machine is wound up on a drum, F, thatturns in bearin gs at the end of frame A, the tension of the paperunwinding therefrom by the action of the winding-up roller beingregulated by an adjustable spring-brake mechanism, d. The paper is thenconducted past a stretchingroller, F and a second roller, F to theroller D and sectional roller 0. The roller F revolves in a directionopposite to the motion of the paper, and may be slightly adjusted in itsbearings, to impart direction and uniform tension to the paper.

The roller F is intended to smooth out any creases or folds that may beformed in the paper, and to secure by moving against the paper the tightrolling of the same on the winding-up roller.

Another advantage of the roller F consists in the fact that any weak andinjured portions of the paper are instantly indicated, as they are notstrong enough to resist the tension exerted by the smoothing-roller. Thedamaged portions are then out out, and the ends connected by gluing.

In this manner the apparatus exercises a perfect control over thequality of the paper, and secures the homogeneous character of theentire roll.

In connection with the winding-up roller are arranged adjustable cuttingdevices G, that trim the edges or cut up the paper into rolls of anydesired width, simultaneously with the rolling of the same.

The cutting devices G are hung by curved arms or frames G to a revolvingtop shaft, G of standards B, and adjusted laterally thereon by collarsand set-screws f. Circular cutting-knives, at the ends of the swingingframes G, are rotated by means of cords or belts g, and intermediatepulleys g, in connection with pulleys 9 that are fastened by set-screwsto the shaft. The shafts of the cutting-knives are eccentricallyextended beyond the frames, and provided with press or guide rollers h,that are adjusted on the eccentric shaft ends by means of set-screws hbearing on the arms or frames G The rollers are lined with cloth, madeof smaller diameter than the cutting-knives, and set by means of theeccentric shafts and screws to greater or less proximity to the paper,to admit the knives to enter more or less into the paper. The knivesadjust themselves by their swinging frames to the increasing size of therolls, and bear, by means of the curved shape of the frames, throughoutthe rolling process on the paper, Whatever be the size of the rolls.

If any one of the knives is not required, the frame of the same is hungto pendent top hooks i of the supporting-frame, in which position, asthe knives continue to rotate, the same may be readily sharpened, andthe press or guide rollers set to the same. The replacing of the kniveshas to be attended to before the machine is started, and also the exactsetting of the knives and their frames to the width of therolls.

The weighted top roller 0 is raised by means of a differential hoistingmechanism, in connection with a shaft, 0, having double end pulleys, theroller being retained in hoisted position, for detaching the rolls fromthe winding-up roller, when the required thickness has been obtained.The sectional roller is then withdrawn, and the rolls removed for beingpacked. They may also be wound on suitable cores, if desired, the coresbeing then mounted in suitable manner.

The apparatus accomplishes thus the rolling and cutting of the paper ina quick, cheap, and uniform manner, so as to be capable of directapplication in the printing-press.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a paper-rolling machine, the windingup roll 0,made in three longitudinal sections, the two outer dovetailed to themiddle one, and the latter arranged to slide in and out of the othertwo, as and for the purpose specified.

2. In a paper-rolling machine, the combination, with the stretching andwinding-up rollers, of a smoothing-roller, that turns in oppositedirections to the motion of the paper, substantially as specified.

3. The combination, with a revolving driving top shaft of apaper-rolling machine, of curved and swinging arms or frames, beingadjustable on the shaft, and having revolving cutting-knives andguide'rollers at the ends, substantially as specified.

4. The shafts of the cutting-knives, having eccentric extensions, withguide-rollers and set-screws, for adjusting the rollers to the requireddepth of the cutting-knives, substantially as set forth.
